Abstract (en)
A thermoplastic olefin elastomer composition which comprises the following ingredients (a), (b), and (c) in amounts of 5 to 93 wt.%, 2 to 90 wt.%, and 5 to 93 wt.%, respectively Ä(a)+(b)+(c)=100 wt%)Ü: (a) a polyolefin resin; (b) at least one of the following ingredients (b1) and (b2): (b1) an aromatic vinyl/conjugated diene block copolymer obtained by hydrogenating a block copolymer made up of at least two polymer blocks derived from an aromatic vinyl compound and at least one polymer block derived from a conjugated diene compound and (b2) an ethylene/ alpha -olefin copolymer rubber; and (c) at least one of the following ingredients (c1) and (c2): (c1) a propylene/1-butene copolymer rubber having a Shore A hardness of 70 or lower and an intrinsic viscosity Ä eta Ü of 0.3 dl/g or higher and (c2) a rubbery copolymer of propylene, a C4-20 alpha -olefin, and ethylene, which has a Shore A hardness of 70 or lower and an intrinsic viscosity Ä eta Ü of 0.3 dl/g or higher.
